() ¡puede venir de aquí!, es la página web de la WHO (*), allí hay un 
faq, publicado ayer, que dice: "  wine influenza viruses are most 
commonly of the H1N1 subtype, but other subtypes are also circulating in 
pigs (e.g., H1N2, H3N1, H3N2). Pigs can also be infected with avian 
influenza viruses and human seasonal influenza viruses as well as swine 
influenza viruses. The H3N2 swine virus was thought to have been 
originally introduced into pigs by humans. Sometimes pigs can be 
infected with more than one virus type at a time, which can allow the 
genes from these viruses to mix. This can result in an influenza virus 
containing genes from a number of sources, called a "reassortant" virus. 
Although swine influenza viruses are normally species specific and only 
infect pigs, they do sometimes cross the species barrier to cause 
disease in humans.
